Atomic Gas Superfluid Might Help Model the Early Cosmos


Quantum physicists have shown that superfluid gases can conduct without experiencing any resistance, possibly paving a way to help model the early Universe in the lab.

The Brightest Flare Ever Observed from Sagittarius A*


The supermassive black hole at the center of the Milky Way, Sagittarius A*, emits relatively little energy for its size, as much energy as Sol even though it’s 4 billion times as massive.

12 Billion-Year Old Supernova Discovered by Astronomers


Astronomers have discovered a pair superluminous supernovae, which are more than 10 billion years old. The Universe was only 3.75 billion years old back then. Of the pair, one is more remote and ranks as the most distant supernova ever discovered.

Mira Supercomputer Will Run Simulation of Our Universe


The advent of the Mira supercomputer, along with more powerful Sequoia and K supercomputers, marks the first time that computers have enough computational power to simulate trillions of particles on the move, running a simulation of the Universe.

Dark Matter Filament in Galaxy Supercluster Directly Measured


A filament of dark matter, which works like the Universe’s backbone, and dictates where galaxies can form, was observed for the first time by astronomers using a technique that could help astrophysicists understand the structure of the Universe.

Gamma Ray Bursts Hold Clues to Chemical Composition of the Early Universe


Gamma ray bursts (GRBs) have been routinely observed by orbiting observatories, such as NASA’s Fermi and Swift spacecraft, and astronomers are planning on using them as cosmic flashbulbs to probe the details of the early Universe. The researchers published their findings in the journal Nature today.

Links Between Core Collapse Supernovae and Star Formation Established


When massive stars accumulate more iron that they can hold, they explode in what is called a core-collapse supernova, also known as Type II supernovae. Such supernovae will enrich their surroundings with key elements, seeding them for the formation of other stars. Now, cosmologists and extragalactic astrophysicists have linked the number of core-collapse supernovae (CCSN) in a galaxy with the actual star formation rate (SFR).
